Panel = Samtec ACRK-22-03-G-S-C-P-1 8 pin (Orange Keyed)
Cable = Samtec ACPK-22-03-G-T-P-1
Pin Direction (Relative to SIR) Function Note
1 Out +24 VDC Power
2 Out COM Power Common
3 N/C
4 In SV RS232
5 Out Reserved
6 Out COM Signal Common
7 N/C
8 N/A SHLD Signal Common
Table 6-8
•
Power is available on Pin 1, Pin 2 (12 VDC or 24 VDC option depending on jumper setting (see
Figure 6-8)) for powering of SV sensor if required:
•
The SV port receives sound velocity data as an AML format string (nnnn.n<CR><LF>) on pin 4 (see
Table 6-8).
•
Communication parameters are set as follows in the SIR unit:
Item Settings
Baud rate 19200
Number of bits 8
